Many AML patients are unable to tolerate intensive chemotherapy and must rely on lower-intensity options, which often deliver limited and short-lived benefit.2 This high-risk, unfit population continues to face a significant unmet medical need, highlighting the urgency for new therapies that can improve survival and quality of life.

"At completion, the acquisition of ImCheck Therapeutics presents an opportunity for us to expand our pipeline in oncology and reinforces our commitment to deliver transformative therapies to the people who need them most," said David Loew, CEO, Ipsen. "We feel confident that with the ICT01 promising data combined with Ipsen’s global development and commercialization expertise, we are well positioned to start a Phase IIb/III trial in 2026."

Interim data (n=45) orally presented at the annual American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 20251 from the Phase I/II EVICTION trial showed treatment with ICT01 in combination with venetoclax and azacitidine (Ven-Aza) achieved very encouraging high responses. In this single-arm trial, treatment response nearly doubled relative to those seen in historical standard of care data across all molecular subtypes in newly diagnosed patients including sub-types typically less responsive to standard of care (Ven-Aza).2 ICT01 in combination with Ven-Aza was also shown to be well tolerated, underscoring ICT01’s potential as a novel immunotherapy to improve outcomes for patients with AML.

"We are thrilled to become part of Ipsen, a company whose ambition for transformative care matches our commitment to bringing innovative treatments to patients. This transaction recognizes groundbreaking science originating from French academia," said Pierre d’Epenoux, CEO, ImCheck Therapeutics. "It also highlights the exceptional work the ImCheck team and our partners have achieved to advance the understanding of butyrophilns and gamma delta T cells. Joining Ipsen will help us accelerate ICT01 toward registrational studies and commercialization. I remain grateful to the patients and investors for their contributions to furthering ImCheck’s pioneering science."

Transaction details
Under the terms of the agreement, through a wholly owned affiliate of Ipsen SAS, shareholders of ImCheck Therapeutics will receive a 350 million euros payment on a cash-free and debt-free basis at closing of the transaction, and deferred payments contingent upon the achievement of specified regulatory approvals and sales-based milestones, for a total potential consideration up to 1 billion euros.

The transaction is expected to close by the end of Q1 2026, subject to fulfilment of customary closing conditions including the expiration or termination of any required regulatory and governmental approvals under French and U.S. regulations.

Advisors
Allen & Overy Shearman (Paris) is acting as legal counsel to Ipsen. Centerview Partners is acting as exclusive financial advisor to ImCheck Therapeutics with Goodwin (London) and Dentons (Paris) acting as legal counsel.

About the EVICTION trial
EVICTION is a first-in-human, dose-escalation (Part 1) and cohort-expansion (Part 2) clinical trial of ICT01 in patients with various advanced relapsed or refractory solid or hematologic cancers that have exhausted standard-of-care treatment options, as well as newly-diagnosed AML. More information on the EVICTION trial can be found at clinicaltrials.gov (NCT04243499).

About ICT01
ICT01 is a humanized, anti-BTN3A (also known as CD277) monoclonal antibody that promotes the recognition and elimination of tumor cells by γ9δ2 T cells, which are responsible for immunosurveillance of malignancy and infections. The three isoforms of BTN3A targeted by ICT01 are overexpressed on many solid tumors (e.g., melanoma, urothelial cell, colorectal, ovarian, pancreatic, and lung cancer) and hematologic malignancies (e.g., leukemia and lymphomas) and are also expressed on the surface of innate (e.g., γδ T cells and NK cells) and adaptive immune cells (T cells and B cells). Binding to BTN3A is essential for the activation of the anti-tumor immune response of γ9δ2 T cells. By altering the conformation of BTN3A, ICT01 promotes this binding, thereby selectively activating circulating γ9δ2 T cells. This leads to migration of γ9δ2 T cells out of the circulation and into the tumor tissue, and triggers a downstream immunological cascade through secretion of pro-inflammatory cytokines, including but not limited to IFNγ and TNFα, further augmenting the anti-tumor immune response. Anti-tumor activity and efficacy of ICT01 have been shown in patients across several cancer indications.

Revolution Medicines to Present Updated Elironrasib Safety and Efficacy Data in Patients with KRAS G12C Non-Small Cell Lung Cancer Following Treatment with a KRAS(OFF) G12C Inhibitor

On October 22, 2025 Revolution Medicines, Inc. (Nasdaq: RVMD), a late-stage clinical oncology company developing targeted therapies for patients with RAS-addicted cancers, reported updated clinical data for elironrasib, a RAS(ON) G12C-selective inhibitor, in previously treated patients with KRAS G12C non-small cell lung cancer (NSCLC) who had received a prior KRAS(OFF) G12C inhibitor. These results will be highlighted in an oral presentation at the AACR (Free AACR Whitepaper)-NCI-EORTC Symposium on Molecular Targets and Cancer Therapeutics in Boston, October 23-25.

"The compelling clinical activity, durable response and acceptable tolerability profile seen with elironrasib underscore the potential of this differentiated RAS(ON) G12C-selective inhibitor, including in patients who have progressed on G12C(OFF) inhibitors," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "These findings reinforce the promise of our RAS(ON) inhibitor platform to deliver a range of therapies that target the active, GTP-bound state of RAS proteins with the potential to create new global standards of care."

As of the August 4, 2025 data cutoff date, patients with KRAS G12C NSCLC, who had received prior therapy with a KRAS(OFF) G12C inhibitor, were treated with elironrasib at the recommended Phase 2 dose of 200 mg orally twice daily (BID) and were evaluated on key safety and antitumor activity endpoints. These patients (n=24) were heavily pretreated, with a median of three prior lines of therapy (range 2-6), with 92% (22 out of 24 patients) having progressed on a prior KRAS(OFF) G12C inhibitor.​ Elironrasib demonstrated compelling antitumor activity, with a confirmed objective response rate of 42% (95% CI: 22-63) and a disease control rate of 79% (95% CI: 58-93). The median duration of response was 11.2 months (95% CI: 5.9-not estimable), and the median progression-free survival was 6.2 months (95% CI: 4.0-10.3). The median overall survival (OS) was not yet reached and 12-month OS rate was 62% (95% CI: 40-78).

These results are from RMC-6291-001, an ongoing multicenter, Phase 1 trial designed to evaluate elironrasib (RMC‑6291) monotherapy in patients with advanced KRAS G12C solid tumors.

Elironrasib is an innovative, mutant-selective inhibitor that binds selectively and covalently to the oncogenic RAS(ON) form of the RAS G12C variant that drives approximately 12% of cases of NSCLC. Revolution Medicines is exploring elironrasib monotherapy and combinations in various treatment settings and continues work to prioritize among multiple options for advancing its development. In July 2025, elironrasib was granted Breakthrough Therapy Designation for the treatment of adult patients with KRAS G12C-mutated locally advanced or metastatic NSCLC who have received prior chemotherapy and immunotherapy but have not been previously treated with a KRAS G12C inhibitor.

NSCLC accounts for 80%-85% of all lung cancers, and most patients have advanced or metastatic disease at initial diagnosis.1,2 KRAS mutations are found in nearly 30% of NSCLC cases, among which KRAS G12C is the most common.

Advancing RAS(ON) Inhibitor Platform Across Tumor Types
Jan Smith, Ph. D., chief scientific officer of Revolution Medicines will also highlight encouraging preclinical data supporting the RAS(ON) inhibitor doublet of zoldonrasib and daraxonrasib during a plenary session at the start of the AACR (Free AACR Whitepaper)-NCI-EORTC Symposium.

Several other presentations to be featured at the meeting demonstrate continued progress across Revolution Medicines’ RAS(ON) inhibitor portfolio, including:

"Targeting the Oncogenic State of RAS with Tri-Complex Inhibitors"
"RAS(ON) Inhibitor In-Pathway Combinations Maximize RAS Pathway Suppression in KRAS Mutant CRC Models"
"Resistance Mechanisms to Monotherapy Daraxonrasib (RMC-6236) in RAS Mutant PDAC"
"RASolve 301: A Phase 3 Study of Daraxonrasib (RMC-6236) vs. Docetaxel in RAS-Mutant NSCLC"
Further details and information on presentations can found on the AACR (Free AACR Whitepaper)-NCI-EORTC Symposium website.

About Non-Small Cell Lung Cancer
More than 197,000 people are diagnosed with non-small cell lung cancer (NSCLC) in the U.S. each year.3 Despite treatment advancements, NSCLC remains a leading cause of cancer-related mortality worldwide, primarily due to its late-stage diagnosis and limited response to conventional therapies.

The multicenter, open-label Phase II study (NCT05167071) enrolled 24 heavily pretreated patients with non-liver-metastatic (NLM) MSS mCRC. Patients received HBM4003 (0.3 mg/kg) plus tislelizumab (200 mg) every 21 days. The primary efficacy endpoint was objective response rate (ORR) per RECIST 1.1 criteria. The findings showed promising antitumor activity and a manageable safety profile for the combination therapy in this difficult-to-treat population.

Key findings include:

Baseline: All patients (N=24) had received ≥2 prior lines of therapy; 16/24 (66.7%) had lung metastases.
Efficacy: Among the 23 evaluable patients, the combination therapy achieved:
Objective Response Rate (ORR): 34.8% (8 partial responses)
Disease Control Rate (DCR): 60.9% (8 partial responses + 6 stable diseases)
Median Progression-Free Survival (mPFS): 4.2 months
Safety: The regimen was well-tolerated, with no Grade 4 or fatal treatment-emergent adverse events (TEAEs) observed.
TRAEs were reported in 87.5% (21/24) of patients, most commonly (incidence ≥20%) liver function test abnormalities, hematological abnormalities, and pyrexia (mostly Grade 1-2).
Treatment-related serious adverse events (SAEs) occurred in 37.5% (9/24) of patients.
Dr. Jingsong Wang, Founder, Chairman and CEO of Harbour BioMed commented: "The 2025 Nobel Prize in Physiology or Medicine was awarded to three immunologists for their groundbreaking discoveries in regulatory T cells (Treg cells) and their role in controlling the immune system. HBM4003, a next-generation anti-CTLA-4 antibody discovered through our HCAb Harbour Mice platform, is a direct clinical application arising from this foundational research. The positive results from this Phase II clinical study mark an important milestone for Harbour BioMed and underscore the therapeutic potential of HBM4003. We will continue to advance HBM4003 with the goal of delivering transformative immuno-oncology therapies to patients worldwide."

About Porustobart (HBM4003)

Porustobart (HBM4003) is a next-generation, fully human heavy-chain-only anti-CTLA-4 antibody discovered and developed using the HCAb Harbour Mice platform. It is also the first fully human heavy-chain-only antibody which entered clinical development globally. Compared with conventional CTLA-4 antibodies, porustobart has unique, favourable properties, including significant Treg cell depletion and optimized pharmacokinetics for improved safety. Additionally, by enhancing antibody-dependent cellular cytotoxicity (ADCC), porustobart increases the potential to selectively deplete intratumoral Treg cells, helping to overcome the efficacy and toxicity bottleneck of current CTLA-4 therapies. The Company has implemented a global development plan for multiple types of solid tumors with an adaptive treatment design for porustobart. Positive efficacy and safety data have been observed in the monotherapy trial targeting advanced solid tumors, as well as in combination trials with PD-1 inhibitors for melanoma, CRC, NEN and HCC. Final data from the study of HBM4003 in combination with toripalimab for advanced HCC were published in Clinical Cancer Research in August 2025.
